2006 STX 12F Fuel Pump Replacement

After 5 great years of service my fuel pump has taken a crap. Have any of you had any luck locating an aftermarket Walbro pump that fits these? Someone told me you could use this pump http://www.customcarscentral.com/wbr...u-wrx-sti.html , but im not sure. I looked up in the microfiche and it looks like kawasaki only sells the entire pump unit and that thing is like 500 bucks. Any help would be much appreciated.
